Where things can and do diverge is the boot mechanism and peripherals, even if it has been getting better with time. (Arm servers and Windows on Arm machines using UEFI + ACPI) However, for user-mode code, compatibility is mandated and checked by Arm, even for designs not made by them. As such, don't worry about it.
